R7140G, L, M Burner Control Modules

The Honeywell R7140G,L,M Burner Control Modules are microprocessor-based integrated burner controls for automatically fired gas, oil or combination fuel single burner applications. The Burner Control Module system consists of a Relay Module, Q520A Subbase, Amplifier and Purge Card. Options include S7800 Keyboard Display Modules (KDM). The R7140 Burner Control Modules directly replace many BC7000 PM720G,L,M, and many R4150G,L,M and R4140G,L,M units using the existing Q520A 20-terminal Wiring Subbase.

The R7140 can be demonstrated or tested on the FSP5004 tester. Note that the R7849 UV Amplifier or the R7851 Optical Flame Amplifier cannot be tested.

The R7140G,L,M is programmed to provide a level of safety, functional capability and features beyond the capacity of conventional controls.

Functions provided by the R7140G,L,M include automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics and troubleshooting.

Features
• Device status available to ModBusTM through S7810M card or S7800A1001 Series 5 Keyboard Display.
• Safety features:
    —Interlock check.
    —Closed loop logic test.
    —Dynamic AMPLI-CHECKTM.
    —Dynamic input check.
    —Dynamic safety relay test.
    —Dynamic self-check logic.
    —Expanded safe-start check.
    —High Fire Purge Switch test (R7140L only).
